MECHANICAL MOVEMENT.

Application filed .Tune 5, 1920, Serial No. 386,829. Renewed November28, 1923.

T 0 all yzllmmr it 'may concern.' 4

Be it known that I, LEROY L. SALFIsnERc. a citizen of the United States,and a resident of Newark, in the county of Essex and State of NewJersey, have invented an lmprovement in Mechanical Movements, of whichthe following is a specification.

The present invention relates to an im-v provement in mechanicalmovements which may conveniently bc applied to packaging machines of thetype adapted to form packages with layers arranged in contiguous zigzagrelation or which may be used indepcndently of another machine toaccomplish a folding or bending operation.

An object of the invention has been more particularly to providereliableand effective means for 'bending or folding into compact packageform an article carrier in strip form and with the articles arrangedtherein in spaced relation, the bending or folding to take place betweensaid spaced articles.

One embodiment of my invention is illustrated in the drawingsaccompanying the present specification, and in which- Figure 1 is afront elevation, and

'Figure 2, an enlarged view partly in transverse vertical section.

Referring to the drawings, a mechanical movement embodying my inventionmay include a reciprocating head 1 slidably mounted in suitableguideways 2 forming a part 'of or secured to a supporting frame 3. Ashaft 4 is. journaled in the frame 3 and carries a gear 5 to which issecured a cam v member 6 having a peripheral cam groove 7 A bell cranklever 8 is pivotally mounted on a bracket 9 in such a position that oneend of the lever will operatively engage the cam groove 7, said endbeing preferably provided with a roller bearing 10. The other end of thelever 8 engages a recess 11 in the reciprocating head 1. Thus, when theshaft 4 is rotated, the peripheral cam groove 7, by means of itsinterior cam surfaces engaging the roller bearing 10, will impart areciprocating movement to the bell crank lever 8, said movement beingimparted in turn and in greater degree to the reciprocating head 1. Thevhead 1 may be provided with a stop 12 positioned to engage a plunger 13having a collar 14 secured thereto, said collar'and plunger beingpositioned to reciprocate within a recess 15 and against resistance of acompression spring 16 surrounding said plunger and having one endengaglng the inner surface of the collar 14.

The head 1 is also provided with a pin 17 upon which is pivotallysupported a carrier 18 having a longitudinal recess adapted to receiveand hold a finger 19, said finger pref- .erably being longitudinallyadjustable with- 1n said holding recess. Thus, the carrier 18 ,and thefinger 19 are mounted to oscillate with respect to the reciprocatinghead 1. To effect controlled oscillation of the finger 19, the shaft 4is provided with a terminal member 20 having a recess adapted to receivethe headed end of a pin 21 secured to or forming' a part of a guide 22which embraces or operatively engages the finger 19. The pin 21 isoffset from the center of the shaft 4 and is free to rotate in itsrecess. ,Thus, when shaft 4 is rotated, the guide 22 will be revolved,giving a throw to the free end of the finger 19. Simultaneously, theinterior surfaces of the cam groove 7 are actuating the bell` cranklever 8 to impart reciprocating motion to the head 1, said motion beingobviously transmitted to the finger 19.

Vhere the .mechanical movement is to be used as a part of a foldingdevice, the parts will b'e duplicated and arranged in such a manner thatthe fingers 19 will be pivoted in substantially vertical alignment andvwith their free ends extending through opposed perforations or guideslots in a guiding box 23 through which passes the strip to betransversely folded. In this arrangement, the gear 5 will mesh with agear 24 mounted on a shaft 25 similar in construction and 'function tothe shaft 4' and carrying at one end a pinion 26 by means of which theshaft 25 is rotated, said rotation being transmitted through the gears24 and 5' to shaft 4.

Referring more particularly to Figure 1, a package, 27 in strip form isshown extending into and through the guiding box 23 and in the path ofmotion of the free ends of both of the ngers 19. These fingers operatealternately and in opposed directions except that the effective stripmoving motion is forward or in the direction of movement of the strip inthe case of each finger. The reciprocating movement of the fingersaccomplishes the bending of the strip and the oscillating movement feedsthe bent portion forward in such a manner that the next increment ofstrip is drawninto proper position for the succeeding bending stroke.

The mechanical movement hereinabove described has operated successfullyas a vfoldin device, permitting the accurate and rapid folding ofpackages of the character hereinabove referred to. Although theforegoing description has been made more partlcula-rly With this use inview, it is obvious that a movement of this character may be adapted toother analogous uses either in the exact form shown or with thesubstitution of equivalent parts obviously contemplated as being Withinthe scope' of the invention described.

I claim as my invention:

1. In a mechanical movement, the combination of a reciprocating member,yan oscillating member pivoted thereto and means for actuating saidreciprocating and oscillating members simultaneously comprising arotatable cam and a bell crank lever havin one end in operativeengagement with sa1d cam and the other end 1n engagement with thereciprocatingmember, a crank pin mounted to rotate with said cam, aguideembracing the oscillating member and operatively secured to thecrank pin, and means for rotating the cam and revolving the crank pin.

2. In a mechanical movement, the combination of a reciprocating member,an oscllating member pivoted thereto, a rotatable shaft mounted adjacentto said oscillating member, a crank pin mounted to revolve with therotation of the shaft and having a guide engaging the oscillatingmember, and means for driving said shaft and for actuating thereciprocating member during oscillation of the oscillating member.

3. In a folding device, the combination of a guideiva)v for the materialto be folded, opposed material bending and moving members operativel)varranged with lespect to said guideivav, and means' for impartingsimultaneous reciprocating' and oscillating motion to each of saidmembers` including a rotatable shaft. a cam on said shaft. a slidabl@head having a pivotal supportfforvthe material bending and movingmember. a bell crank lever operativel)v arranged bctween the cam and theslidable head, a crank pin carrier secured to the shaft and having acrank pin revolublY mounted therein and guiding means in sliding en-Agagement with the. material bending and moving member and revolvablewith the pin carrier. d l

In testimony whereof, I have signed my name to this specification thissecond day of June, 1920.
